CVE-2026-102069
Junos OS: An ICCP peer causes dot1xd to crash when dot1x synchronization is enabled
Published Oct 14, 2026 · updated Oct 15, 2026 · Juniper Networks Junos OS
A Stack-based Buffer Overflow vulnerability in the dot1x daemon of Juniper Networks Junos OS devices operating as Junos Fusion Aggregation Devices allows an adjacent attacker acting as the configured ICCP peer to cause a denial of service and potentially execute code as root via. The issue is triggered when dot1x synchronization is enabled for the required Fusion satellite topology.
